NASA Recorded the Sounds of Mars (And It's Almost All Creepy Bass)

NASA Recorded the Sounds of Mars (And It's Almost All Creepy Bass)

The air pressure sensor inside the shield will be relocated as well, and the team will gather data at night, when it expects the wind will have died down and the lander itself will be making less noise.

There are more plans to record sounds on Mars with the 2002 lander project.

InSight's seismometer captured the vibrations. But this is the first time we've ever heard what Mars sounds like.

The Seismic Experiment for Interior Structure (SEIS), the seismometer, will use the vibrations to help scientists configure more about the planet's interior. What has been captured is the sound of the red planet - distinct, low, humming winds.

The Instrument Deployment Camera (IDC), located on the robotic arm of NASA'sInSight lander, took this image of the Martian surface the day the spacecraft touched down on the Red Planet, and was relayed from InSight to Earth via NASA's Odyssey spacecraft, now orbiting Mars, on November 26, 2018.

Nasa said that the air pressure sensor used to collect meteorological data recorded these air vibrations directly.

This is brilliant news because it means we know the sensors have survived the rigours of landing on Mars and are meeting the requirements to achieve their science goals.

InSight's seismometer and another sensor picked up the noise, and it was not planned.

The vibrations have been shifted up into the human audible range, and sped up so that we can make sense of them, but it really sounds like if you were sitting on the lander's deck, hearing the winds whistle by your ears! "The solar panels on the lander's sides respond to pressure fluctuations of the wind".

"This is the very first 15 minutes of data that have come from the short period seismometer", said Thomas Pike, lead investigator at Imperial College London, during a conference call with reporters.

InSight will see if tremors, or marsquakes, have a similar effect on Mars. It still will detect the lander's movement, though channeled through the Martian surface. "It's going to become very hard to hear the sounds from the outside of Mars later on". "When we looked at the direction of the lander vibrations coming from the solar panels, it matches the expected wind direction at our landing site". A second will be able to detect the sound of the instrument's laser as it zaps different materials.
